UP:MA19.K.8

Vocabulary

  • Expression
  • Equation

Knowledge

Students know:
  • how to represent addition and subtraction using models, pictures or symbolic representations.
  • how to explain representations of quantities.

Skills

Students are able to:
  • Represent quantities and operations physically, pictorially, or symbolically.
  • Use informational and mathematical language to communicate the connections among addition and subtraction.

Understanding

Students understand that:
  • both putting together and adding to can be viewed as addition.
  • both taking apart and taking from can be viewed as subtraction.

Learning Objectives

I can represent addition and subtraction up to ten by using verbal expressions and symbols to represent my thinking.

Activity Details

The teacher will display the slideshow How Many More to Make Ten?. The students will view each image and quickly decide how many more of the displayed object is needed to make a quantity of ten. 

The teacher will say: "In this activity, you will look at some pictures. In each picture, there is a number represented by objects. Look at those objects and decide how many more are needed to make ten. You will show me your answer by quietly holding up the number of fingers to represent your answer or raise your hand to tell me your answer in words."

Example: Slide two is a picture of five fingers. The teacher will say, "How many more fingers are needed to show ten? Show me your answer by quietly holding up the number of fingers to represent your answer or raise your hand to tell me your answer in words."

Assessment Strategies

Teachers will observe student responses to determine student understanding of the concept and skill. You can use the following guidelines to ensure students meet the learning objective.

Check that the student:

  1. can recognize that numbers can be shown in many ways.
  2. can use a strategy to add up to ten.
  3. can count on, rather than counting each object.
  4. can represent their answer with a symbol or verbally.

Variation Tips

The teacher can expand on these images as students' understanding of addition and subtraction deepens. Instead of how many more objects are needed for ten, the teacher can use larger total quantities such as 15 or 20.

Background / Preparation

The teacher will need a projector and computer to show the Google slideshow.
